1. A communication method of an apparatus in a wireless communication system, the communication method comprising:
transmitting first downlink control information (DCI),
wherein a type of a hybrid automatic repeat request-acknowledgment (HARQ-ACK) codebook is determined to be a specific type based on a 1-bit flag based on the first DCI; and
receiving HARQ-ACK information for a physical downlink shared channel (PDSCH) in the HARQ-ACK codebook based on the type of the HARQ-ACK codebook being the specific type, wherein the PDSCH is scheduled by second DCI and the second DCI is transmitted before the first DCI,
wherein, based on the type of the HARQ-ACK codebook being the specific type, the first DCI does not schedule a PDSCH and whether the HARQ-ACK information is transmitted is determined based on a specific field included in the first DCI, and
wherein the specific field is different from the 1-bit flag.
